Be it knoivn that I, PAUL B. Finnen, a citizen lof the United States, residing at Chicago, in the county of Cook and State of illinois, have invented a certain neiv and useful improvement in Tracker-Boards and Illusie-Sheets, of which the following is av full, clear, concise, and exact description, reference being had to the accompanying f drawings, forming a part of this specification.

My invention relates to instruments employing traveling music sheets and tracker oards therefor, such for example as piano players, player pianos and the like.

rlhe invention contemplates a novel form of tracker board having particular advantages and especially useful in connection with a certain type of instrument to be referred to hereinafter.

ln the accompanying drawings, Figure 1 is a vieiv of a portion of a music sheet and tracker board embodying my present invention; F ig. 2 is a similar view of a modified form; 3 is a longitudinal section through one of the sets of ports of the tracker board; and F ig. el is a transverse section of the tracker board.

`Referring first to F ig. 1, show a tracker board 1 and a music sheet 2 traveling over the saine. The tracker board 1 is provided with apertures or ports 3& 82 which are connected together in pairs as shown in Fig. 3, each pair being connected ivith a duct or channel 7. Apertures or ports 1 l are arranged in the rear of the apertures Sa, an aperture l being in the rear of one of the apertures Pf- 8a of each pair. A pair of apertures ia-3 with an aperture 1l lie in a single note zone.

The music sheet 2 is provided in this form with perforations 5 5 and 6 6. r`fhe apertures 5 5 open one of the front perforations 3'L1 of the various pairs, and the perfora tions 6 6 open the other or associated aperture 8a of the pairs and also the corresponding or associated rear aperture. The tracker board and music shee thus set forth can be used in various Ways and in connection With various instruments. @ne very advantageous use Would be in connection ivith the apparatus of Patent No. 899,469, issued September 22, 1908 to Pierce, or in connection with the apparatus of latent No. 1,183,210 issued May 16, 1916, to inyself.

n such case the front apertures 3 through the channels or ducts 7 7, would be connected ivith suitable note striking or sound producing apparatus and the rear apertures 1 1 With apparatus or mechanism for modifying the tones or notes produced or sounded. Thus the perforations vvould sound the notes only and the perfor-ations 6 6 Would not only sound the notes but would modify the same as Well, making the same softer or louder as desired. if made louder the perfor-ations 6 6 would have the eiiect of being solo perforations.

ln Fig. 2, 1 show the same tracker board 1 but a different form of music sheet 21. 1n this music sheet there are perforations 5 5, as before, and there are also perforations' s a which are relatively wide and so open not only the rear apertures 1 1 but both of the corresponding front apertures 3a 31, instead of only one of the latter as in the foregoing' modiiication.

lt will be understood that changes and modications can be made Without departing from the invention.

What I claim is:

1. A tracker having a plurality of ports side by side for a single note, and channels uniting said ports into a single unobstructed passage, and another port in transverse alinement with one of the first named ports for modifying the action of the same note sounding mechanism.

2. ik tracker haif'ing a double aperture therein and au elongated aperture in the rear of part of the double aperture, for modifying the action of the same note sounding mechanism, the parts of said double aperture being connected together.

tracker having a double aperture therein, and an aperture for modifying the action of the same note sounding mechanism, cooperating with said iirst named aperture in such a` position in said tracker that said last named aperture is opened before said first named aperture, the parts of said double aperture being connected together.

if. The combination of a tracker having a plurality of ports for the same note arranged at the side of one another lengthrise of the tracker and also having a port for modifying the action of the same note sounding mechanism in the rear of one of the aforesaid ports, and a music sheet having peiforations some of which are adapted to open one or the aforesaid plurality oi' ports and the port in the rear thereof and Vothers of which are adapted to open another of said plurality of ports'.

A tracker having a plurality of ports side by side longitudinally of the tracker, -and channels Auniting said ports into a singie unobstructed passage, and another port in transverse alinement withv one or the firstl named ports for modifying the action of' the same note sounding mechanism as the first nai-ned ports. G. tracker having double apertures whereof each double aperture lies in a single note Zone and whereo't the two parts of' each double aperture are connected together, said 'tracker also having an aperture'in Vthe rear of' one part ot' each of said double apertures, in combination with a music sheet having narrow perforations, each for opening one part oi double aperture and the aperture in the rear thereof, and other narrow perforations, each for opening only one part off' a double aperture.

7. tracker having a plurality of ports arranged in note Zones, a single note zone comprising a plurality ot' portsV arranged side'by side longitudinally of' the tracker, .channels uniting said ports, and another port in transverseV alinement with one of the first named ports. Y

8. je. tracker having a plurality of ports Varranged in note zones, a single note Zone comprising a pluralityV oi ports arranged side by side longitudinally oi the tacker, channels uniting said ports, and another port in transverse alinement with one of the iirst named ports, in combination Vwith a music sheet having Vnarrow perforations for opening one'oi" the first named ports and the port in YtransverseV alineinent therewith and other narrow perforations for opening the other ofthe first named ports.

9. A tracker having a series of ports arranged in line lengthwise of the tracker, said ports being arranged in groups, and a second series ofports transversely displaced with reference to the first mentioned series, there being a port in said second series for each group of ports in the iirst mentioned series.` Y Y 10. fr tracker having a series of apertures arranged lengthwise of the tracker in ,alinenient with one another, there being two apertures .for each note, and a second series 'of' apertures `transversely displaced with reierence to the first mentioned series, there being one aperture for each note in said sec-.

Vond series.

V11. A tracker having a series of alined apertures extending lengthwise of the tracker, there being 'two apertures for each Copies of this patent may be obtained for note, and a second series of apertures in the rear or said lirst named series', there being one aperture for each note in `said second series. Y

12. A tracker having a series of alined apertures extending lengthwise of the tracker, there being two Yapertures for each note, and a second series of apertures in the rear of said first named series, there being one aperture for each note in said second series, which said aperture is in transverse alinernent with one of the apertures of said first named series.
